IPC: G11C7/22

Granted: 2007-08-08
Abstract: A system and method is disclosed for writing early within a memory cycle by holding only one of a true bitline and a reference bitline at a fixed potential, e.g. ground, when the sense amplifier is set. The sense amplifier amplifies a small voltage difference between the true bitline and the reference bitline to predetermined high and low voltage logic levels to write a datum to the memory cell. In this way, writing can complete in about the same time as reading, without risking corruption of data on adjacent bitlines in the memory. The bitlines are precharged to a fixed potential in a conduction path through the bitswitches, rather than using local precharge devices at the sense amplifier. To write, bitswitches and write path transistors apply the fixed potential to one of the true bitline and the reference bitline. Bitswitches on such other memory cells not currently being written isolate the bitline pairs coupled to those memory cells when setting the sense amplifiers, such that the stored contents of such memory cells not being written are refreshed (written back) at the time that the selected memory cell is written.

Abstract: A textile garment in the form of a bra or ladies top is produced from a knitted component ( 11 ) formed using a circular knitting technique, with the component ( 11 ) formed as one piece comprising a first part ( 11 a) and a second part ( 11 b), the shape of the second part ( 11 b) being generally a mirror image of the shape of first part ( 11 a) when viewed with respect to a dividing line ( 12 ) disposed half way along the tubular construction. The knitted construction is produced from yarns which are electrically insulative. However, two regions of the knitted construction ( 11 ) include electrically conductive yarns to form electrodes ( 15 ). Conductive yarn is also used to produce conductive tracking ( 16 ) leading from each electrode ( 15 ). The second part ( 11 b) is lifted up to fold the knitted construction at dividing line ( 12 ) such that the second part ( 11 b) forms an outer layer while the first part ( 11 a) forms an inner layer. Thus the conductive electrode forming regions ( 15 ) become part of the inner layer, where they are electrically insulated by the outer layer.
